Goes without saying, but the art in this is incredible. Spectacular. (Though I agree that the stark white square player was a bit jarring among all the beautiful scenery.)

The parallax also looked really nice, though I would have liked some damping on the movement. For my eyes/sinuses.

In terms of controls, I would have liked to have a separation between the clicking to find things and the moving; I was often clicking on things to see if it's a thing, and then moving. It's not a huge deal, but a little annoying. (E.g. having left click be for selecting things and right click for moving would have solved this.)

I also wonder if it would have felt cooler to have the player add the plants to the book by examining things rather than already knowing all the ones they're looking for? (Or a textual description, which turns into a sketch once you find it?) I think a sense of discovery is paramount to what this game seems to be about, so leaving a bit more mystery to start out with might have been good? (Also, I feel like my ability to come up with a good name for a plant massively improves once I see the poem; i.e. having the players "discover" new plants and only then sketch and name them would have been cool.)

I think I made it to the end; your description says I'll unlock a poem if I find all the plants, but I don't think I did (unless you meant the individual poems for each separate plant, which I did enjoy for all four). 

Anyway, what a beautiful and chill experience. Very cool.

I agree with Zirk. Visuals and artwork is awesome. There was a white square in the middle of the screen, not sure if it was suppose to be there. It distracted a bit from the experience, but not game breaking. Well done overall. 

Visually very cool! Music gives a great calming vibe, all I could think about was who drew all the pictures in the booK. Not a lot of narrative but I think it's a very cool game very calming

Love the vibe, and the way it all fits together. It's a really nice proof of concept, and I reckon that all of it can be expanded nicely.

For me, the experience felt more like I was collecting poetry, and I think that should be leaned into. Maybe as you explore you collect vocabulary (inspiration), and then you let players put that together fridge-poetry-style. Alternatively you could do something like the poetry or songs in Kentucky Route Zero.

Also, I hit a few bugs with the book. I got the wrong flowers popping up in the book after interacting with the environment. It might have something to do with the sequence of interaction? And that's totally variable from the player's perspective where the goal isn't clear from the beginning.

Music is sweet, art is fire. Probably your best work yet! Totally love the book illustrations. For me, I want more book time.
I think it's not quite clean enough for a writing-prompt game (see Trawl), and not quite deep enough for an exploration/discovery game, but it could go either way, or both, and maybe some proc-gen would do it good in both areas.
